Not really. Look into studying body language. People have 'tells' and subtle cues which we could pick up on as indicators. Otherwise, empaths might be able, like someone's happy and telling jokes, but the empath can feel sadness or anger from them. You can't see if someone's a liar by looking at them. Some aura colours I'm told can indicate emotion or health, but no sign will appear saying 'liar'.

you sync yourselve with that person do it right and you will sanse what you need to know, don't let your personal feelings cloud your senses, oh my gosh i think I'm ripping of jedi on this one, still works give it a try.
